03/09/2018 Gamma Spectroscopy with Silicone Photomultiplier SiPM MicroFC 60035 SMT and CsI(Tl) scintillation crystal

MicroFC-60035-SMT manufactured by Sensl is 6x6mm SiPM silicone photomultiplier sensor. The C series 60035 has P-on-N type structure and used for blue range light, that's why it fit perfectly CsI(Tl) scintillation crystal. The circuit works as an amateur gamma spectroscopy detector for 192kHz audio card MCA.

07/07/18 BecqMoni2011 English User Manuals PDF files

The page was created in attempt to help users to understand and set the main settings of the BecqMoni MCA program. I'll add the further links to PDF files with instructions. All these documents are prepared in my freetime and it represent only my personal experience. You are welcome to contribute.

28/04/18 DIY Multi Channel Analyzer MCA project with NaI(Tl) Gamma Spectroscopy Detector

Article describing work-log process of assembling portable battery operated MCA with NaI(Tl) detector. The device has good linearity and FWHM% resolution less than 8%. The circuit evolves high voltage for a photomultiplier tube, it has analog electronics to process pulse shape and it has digital electronics to count pulses and analyze spectra.

14/06/17 How to make DIY Gamma Spectroscopy Detector for iPad or Computer Audio Card - Собираем спектрометрическую приставку для компьютера и iPad

Любительской гамма спектрометрией я увлекся в начале 2015, когда измерять уровень радиации обычным дозиметром стало уже не интересно и захотелось заглянуть поглубже чтоже там на самом деле происходит. Сразу оговорюсь, что представленный в статье прибор не является профессиональным лабораторным гамма-спектрометром так как имеются некоторые ограничения. Но, несмотря на это, с помощью такой приставки можно легко определять радионуклиды излучающие гамму в пределах 13кеВ-1700кеВ.

23/11/15 HF SSB Superhet 20M Receiver with DDS option and Active Hula Loop Antenna

The receiver is a simple superheterodyne type with quartz crystal filter. The circuit is based on two NE612 mixer IC’s and one audio amplifier LM386. The electrical circuit as it described below in the manual is intended for 14.000MHz – 14.350MHz upper single side band receiving of amateur radio transmissions. It has compatibility with AD9850 DDS and active loop antenna.

14/05/15 PINRAD Gamma Photon Nuclear Radiation Detector with PIN Diode

As you know, PIN diode can be used for detection of gamma radiation. Maxim Integrated announced a good materials for the experimental building of such type detector. Here you can find my implementation, including oscilloscope screenshots and short video.
